Frequent Questions

Are drinking water additives, such as chemicals used for fluoridation and coagulation, regulated by the Safe Drinking Water Act?

The Safe Drinking Water Act does not require EPA to regulate the use of additives in drinking water. Originally, EPA assisted states and public water systems with the use of water additives; however, in 1988 EPA established a cooperative agreement with NSF International to develop voluntary consensus safety standards for drinking water additives (53 FR 25586, 25586; July 7, 1988).
